Interacting new generalized Chaplygin gas

TL;DR

This paper proposes a cosmological model where a new generalized Chaplygin gas interacts with matter, leading to stable late-time solutions and phantom crossing behavior, which could explain the universe's accelerated expansion.

Contribution

It introduces a novel interacting model of the new generalized Chaplygin gas with matter, highlighting stable scaling solutions and phantom crossing phenomena.

Findings

Existence of stable late-time scaling solutions

Observation of phantom crossing scenario

Potential implications for cosmic acceleration

Abstract

We have presented a model in which the new generalized Chaplygin gas interacts with matter. We find that there exists a stable scaling solution at late times in the evolution of the universe. Moreover, the phantom crossing scenario is observed in this model.
